Product Analysis: Koganei AFDPG-6 Air Hand
The Koganei AFDPG-6 is an ultra-compact, 6mm bore parallel air hand designed for the micro-automation sector. This miniature gripper is one of the smallest high-precision actuators available, specifically engineered for handling electronic components, medical samples, and microscopic mechanical parts. Despite its miniature size, the AFDPG-6 incorporates a sophisticated linear guide and double-piston design to provide reliable, repeatable gripping force in an incredibly thin body.
Miniature Precision and High Performance
The core philosophy behind the AFDPG-6 is «miniaturization without compromise.» It achieves a theoretical gripping force of 12N at 0.5 MPa, which is exceptional for its 6mm bore size. The integrated linear guide ensures high rigidity, preventing finger deflection during high-speed lateral movements. This makes it the ideal choice for high-speed assembly machines where the space between components is measured in millimeters. Its thin profile allows for multiple grippers to be mounted side-by-side on a single manifold or robotic head.

Advanced Design and Mounting
The AFDPG-6 is designed for easy integration into high-density automated systems. It features M3 x 0.5 piping ports and mounting threads on three surfaces, allowing for creative mounting solutions in tight spaces. Despite its small size, it remains compatible with miniature sensor switches for position confirmation. The aluminum alloy body is hard-anodized for wear resistance, ensuring that the gripper maintains its precision over millions of operations in cleanroom environments.

Technical Note
When using the AFDPG-6, it is critical to use properly sized gripping fingers to avoid exceeding the allowable moment of the linear guide. Due to its miniature components, over-tightening the mounting bolts or the finger attachments can cause mechanical distortion; always follow the manufacturer’s torque specifications for M3 hardware.
